Yay! Finally I have sources to look at. "Vehayisa akh sameiach" just
became a little easier.

Does anyone have "Mussar Avikha", "Uvdos veHanhagos miBeis Brisk" (vol II
p 50) and/or "Orchos Yosheir" (#13)? Do any of them discuss mezuzah and the
consequent shemirah, or any of the other related segulah-like effects
of mitzvos we've tied in to previous iterations?

Look at that list of names: I'm not wrong, just Litvish!

Tangent: The Gra said that "vehayisa akh sameiach" is the hardest mitzvah
in the Torah. "Veyahisa sameiach" is one thing, but "akh sameiach"? To be
nothing but happy, with no other moods ambivalently mixed in for 8 days
(9 in chu"l) straight?

Tir'u baTov!
